Title: A process for dyeing pelts, furs or the like
IPC: D06P3/30
Filed: 1933-06-02
Abstract: Aniline-black and like dyeing.--Hairs, pelts, furs or feathers are dyed by treatment, in a neutral acid or alkaline medium and with or without a mordant, with a diamine of the benzene series containing sulphur in the form of an alkyl mercapto group and with an oxidizing agent.  Substances known to yield oxidation dyeings, such as chloro- or nitro-p-phenylenediamine, 4 - dimethylaminoaniline, 4 - amino - phenol, 2-nitro-4-aminophenol, 4-chloro-2-aminophenol, 4 : 4<1>-diaminodiphenylamine and 4-dimethylaminodiphenylamine, may also be present.  The diamines containing sulphur may be further substituted, e.g. by halogen, alkyl, alkoxy or hydroxy groups.  The following examples are specified.  (1) White rabbit skins, mordanted with a salt of chromium, copper or iron, are dyed a bright clear greenish black by treatment for three hours with an aqueous solution containing the hydrochlorides of p-phenylenediamine and 2 : 4-diaminoethylmercaptobenzene, with an addition of ammonia to bind the hydrochloric acid, and hydrogen peroxide.  (2) White rabbit skins, mordanted with a salt of chromium or copper, are dyed a clear greenish-black by treatment for three hours with an aqueous solution containing p-phenylenediamine, 2 : 4-diamino-b -hydroxyethylmercaptobenzene and hydrogen peroxide. (3) A chromium-mordanted skin is dyed a dull bluish red-brown by treatment with an aqueous solution containing 2 : 5 - diamino - 4 - ethyl - mercaptoanisol and hydrogen peroxide; a copper-mordanted skin is similarly dyed a greyish-brown and an iron-mordanted skin a dark grey; if the diamine is replaced by 2 : 5 - diamino - 4 - ethylmercapto - chlorobenzene dyeings with a yellowish tinge are obtained.  (4) A white rabbit skin, mordanted with copper, is dyed a clear yellowish-brown by treatment with an aqueous solution containing 5-amino-2-b  : g -dihydroxypropylamino-4-ethylmercaptochlorobenzene and hydrogen peroxide.  Diamines substituted by two alkylmercapto groups, e.g. 1 : 3 - diamino - 4 : 6 - di(ethylmercapto)benzene and 1 : 3 - diamino - 4 : 6 - di(b  - hydroxyethyl - mercapto)benzene, may be used. According to the Provisional Specification aromatic diamines in general substituted by alkyl-, aryl- or aralkyl-mercapto groups may be used.  Diaminobenzenes substituted by alkylmercapto groups are obtained by treating the corresponding diamines containing one or more exchangeable substituents with the corresponding alkyl mercaptans or by similarly treating the corresponding substituted nitro compounds and thereafter reducing the nitro group or groups; thus 2 : 4 - diaminoethylmercaptobenzene is obtained by reducing the product of reaction of 2 : 4-dinitrochlorobenzene with ethylmercaptan and 1 : 3-diamino-4 : 6-di(ethylmercapto and b  - hydroxyethylmercapto)benzenes are obtained by reducing the products of reaction of 1 : 3 - dinitro - 4 : 6 - dichlorobenzene with ethylmercaptan and b -hydroxyethylmercaptan respectively.

Title: Improvements in or relating to apparatus for grading articles by weighing
IPC: B07C5/18
Filed: 1942-11-13
Abstract: 561,774. Grading by weighing. WEBB, Ltd., W. A., and BEAL, A. W. Nov. 13, 1942, No. 16087. [Class 143] In an apparatus for grading glass tubes or other articles by weighing, the articles are fed successively to a holder carried by a damped balance beam and, when the beam comes to rest, are pushed by a transfer device through a selected aperture in a column thereof according to the depression of the beam, the articles being positively registered with the selected apertures before or during their transfer. In the form shown, for use in grading glass tubes, a rotary feeder 14 transfers the tubes successively to the notched end of a weighbeam 1 which is consequently depressed to position the tube according to its weight adjacent to one of a column of delivery shoots 4. Tapering pins 22 on a slide 23 move into engagement with a pin 24 on the weighbeam to ensure precise registration of the tube with a shelf which then receives the tube as it is pushed off the weighbeam by a pair of cam-operated arms 19. Instead of employing the slide 23 to ensure the correct transfer of tubes from border-line positions, the arms 19 may be provided with tapering pins which, on the forward movement of the arms engage the tubes and either lift or depress them sufficiently to ensure their correct transfer. A battery of weighbeams and associated feed and transfer devices arranged side-by-side may be employed to increase the output.

Title: Improvements in and relating to means for controlling self-propelled railway and other vehicles
IPC: B61C5/00
Filed: 1925-06-22
Abstract: 258,645. Brill Co., J. G., and Guernsey, C. O. June 22, 1925. Addition to 258,362. Controlling-apparatus, arrangements of transmission gear in conjunction with. - Controlling means connecting an operating lever on the body of a motor vehicle to gear-selector means on transmission mechanism pivoted to the body are not affected by relative movements between the body and the transmission mechanism. As described in the parent Specification the body 4 is pivoted on a bolster 6 forming part of a truck structure 2. The change-speed gear is enclosed in the bolster and has five speeds obtained by moving gear-forks 10, 11, 12, Fig. 5, one at a time, from their central positions. The forks are on sliding shafts 13, 14, 15 carrying arms 19, any one of which can be operated by a selector arm 22 fixed on a transverse shaft 23. One end of this shaft is carried in a sliding spherical bearing 33 on the gear-box and the other end is supported by a ball joint 36 on arms 32 fixed to a longitudinal shaft 31. The front end of the shaft 31 has a hand lever 29 pivoted to it at 30, the lower end of this lever having a transverse sliding connection with a universally - jointed link 25, the rear end of which is pivoted to an arm 24 fixed on the shaft 23. Transverse movement of the lever 29 rocks the shaft 31 to move the shaft 23 endwise so that the arm 22 selects one of the gear forks; fore-and-aft movement of the lever 29 then moves the link 25 to rock the shaft 23 and shift the selected gear fork in one direction or the other. Movements of the body relatively to the truck and the gearing cause a rocking movement of the shaft 23 more or less about the arm 22 as centre so that the gearing control is not affected thereby. In the construction shown in Fig. 7 a gear-fork 10<a> is shifted by a rod 13<a> having a roller 41 engaging in a cam-slot formed in a sliding plate 38 and operated by a link through a bell-crank lever 39 mounted on the gear-case. The cam-slot is formed with three flat portions 42, 43, 44 corresponding to the three positions of the gear, these portions being connected by inclined or cam portions 45, 46. Normally the roller 41 occupies the middle part of one of the flat gear portions 42, 43, 44 so that slight movements of the cam plate caused by movement of the body relatively to the truck and the gearing merely cause the roller to move along this flat portion and do not affect the gear fork itself. Only one gear fork is shown, but it is stated that more than one may be controlled in this manner. In a modification the sliding cam plate is dispensed with and corresponding curved cam-slots are formed in one arm of a lever taking the place of the bell-crank lever 39.

Title: Improvements in or relating to the automatic tuning of wireless receiving apparatus
IPC: H03J7/04
Filed: 1937-06-10
Abstract: 492,408. Automatic tuning correction. GENERAL ELECTRIC CO., Ltd., and STENNING, L. C. June 10, 1937, No. 16170. [Class 40 (v)] The Specification relates to thermionic reactances of the type described in Specification 443,423 and is devoted to certain modifications in a reactor of this type to render it suitable for operation at frequencies of the order of 10 megacycles. The control grid-cathode circuit of the screen grid valve 1 is connected across the tuned circuit 4, 5, to be controlled, the anode being connected to the control grid through a resistance R1, screened at 11 to avoid stray capacity, and condenser C2. The anode is connected to HT+ through a condenser C1 shunted by resistance R2. The A.F.C. bias voltage may be applied to the screen grid or, as shown, to the control grid. With this arrangement, the Specification shows mathematically that if C1 is made greater than (1/R1+1/R2) and C2 is greater than C1 then the input admittance of the control grid-cathode circuit varies with the mutual conductance of the valve and the reactor is thus effective at frequencies greater than 10 mc.

Title: Improved machine-gun or similar automatic fire-arm
IPC: F41A5/02
Filed: 1943-10-08
Abstract: 601,376. Automatic guns. ROBINSON, R. S. Oct. S, 1943, No. 16548. [Classes 92 (i) and 92 (ii)] An automatic gun fired during run-out, and in which the reactions on the gun frame during the firing cycle are smoothed out, comprises a barrel B, Fig. 2, which recoils against the action of a recuperator spring 2 that applies an uninterrupted rearward thrust to the gun frame throughout the whole of the recoil and run-out, the gun having a transversely-sliding breech block C, a cartridge-feed mechanism I and a spring-pressed rammer H which are timed to function within the period of uninterrupted recoil and run-out. In the form shown, the gun, Fig. 2, is in the run-out firing position, the recuperator spring 2 is connected with the barrel by a bell-crank lever 5, 6 and link 9 to equalize the spring force and the transverselysliding breech-block C is connected with the barrel by a bell-crank lever D the elbow 17 of which engages a cam groove 18 in the gun casing. The barrel-extension B<SP>1</SP> supports a pair of levers 47, 50 pivoted respectively at 48, 51 and connected by a tension spring 53. The lever 47 serves by its nose 49 to extract a live cartridge 39<SP>1</SP> from the belt on recoil thereby stressing the rammer 54 that presses against the cartridge the base of which is guided by a fixed cam 58 until the nose is turned to rest on the upper-shaped part of lever 50 which turns and guides the cartridge towards ' the gun chamber, Fig. 4. When a roller 59 on the Lever 47 eng ges a fixed cam surface 60, the nose 49 is di engaged from the cartridge which is then rammed into the chamber along the guide on lever 50 by the rammer 54. The barrel is then either retained in rear position by a sear E or, in the case of continuous fire with sear withdrawn, runs out towards the firing position shown in Fig. 6 in which the firing pin 23 is actuated by a tripping-lever 25. This lever, pivoted at 27, has a projection 28 engaging a surface 31 on the gun casing and a second projection 29 entering a recess 32 in the casing. On recoil, the projection 29 engages a surface 33 to retract the firing pin and the breech-block is lowered by the lover D engaging the cam groove 18. The cartridge belt is fed by a pawl on a feed-slide 34 that is reciprocated by engagement with a cam groove 37 on the barrel. The belt links 40<SP>1</SP> are supported in a stripping chamber 41 during extraction of a cartridge by the lever 47. The empty case is guided during ejection by the shaped undersurface of the lever 50.

Abstract: 1499007 Transistor amplifiers SONY CORP 22 April 1975 [25 April 1974] 16635/75 Heading H3T A wire suppression circuit comprises a semiconductor device having, connected to terminals, three regions of alternating conductivity type with, separated from the first (emitter E) region by a thin insulating layer, a fourth (gate G) terminal modifying the common-emitter amplification factor h FE  as the bias between terminals G and E is varied, so that h FE  has a regime of high constant level leading by a slope to a lower level, the noisy signal being applied to the second and fourth terminals, an output terminal providing a signal with noise peaks compressed. In Fig. 6 first, second and third regions form the emitter E, base B, collector C of a bipolar transistor, the first region possibly containing a potential barrier formed by a region of higher impurity content within the minority carrier diffusion distance from the EB junction. The NPN configuration shown may be reversed. The h FE  characteristic as a function of V GE  has a V-shaped symmetrical valley (Fig. 5, not shown). The negative-going signal Sv, possibly video, applied at 21 is passed to output 26, the nett gate bias-E1 ensuring that the signal is amplified with full gain except for noise peaks S n  which make V negative enough to reduce h FE . For positive going signals (Figs. 8, 9, not shown) the emitter bias resistor 24 is removed, the base being biased positive by a potential divider across the supply to compensate; a more negative nett bias on the gate then allows noise peaks to enter the valley from the negative side.
